A 16 channels heterodyne radiometer is being developed on HT-7 superconducting Tokamak. The received frequencies of the radiometer are from 98 to 126 GHz. The local oscillators are 95 GHz for the low field side and 108.5 GHz for the high field side. After using the SSB mixers, the frequency is down converted to 2-18 GHz and detected by the detectors. The spatial resolution of the system is about 2cm...
Fusion plasma density can be measured by FIR laser and submillimeter wave interferometer. The DCN laser has the highest specific output power among known submillimeter electricdischarge lasers. Its output characteristics fit the requirements for interferometric measurements on large tokamaks. So that, the continuous wave (CW) discharge-pumped 1.54 THz (195 mum) and 1.58 THz (190 mum) deuterium cyanide...
Reflectometry is a technique, based on the radar principle, with a response mainly sensitive to the plasma regions where the microwaves are reflected. The reflectometry technique used in plasma devices measures the phase of a wave reflected by a plasma cut-off layer at a given electron density. It has become a promising experimental technique for the measurement of the electron density profile in...
Trace-driven simulation is an important technique used in the evaluation of computer architecture innovations. However using it for studying parallel computers and applications is at best very challenging. Acquiring, representing and storing the traces are among the major issues. In this paper, we introduce path grammar guided trace compression (PGGTC) and effective address trace approximation (TA)...
This paper describes an approach to the use of neural networks for improving the scientific paper classification performance. On the basis of the initial classification results obtained from the content-based naive Bayes method, this approach uses neural networks to model the citation link structures of the scientific papers for refining the class labels of the documents. The approach is examined...
Signs of long-term glaciological processes and past ice-sheet structure are preserved in the internal layer manifestations of the Greenland ice sheet. Internal layer data have been collected over a substantial portion of the Greenland ice sheet using the University of Kansas ice-sounding radar. In this letter, these layers are traced along thousands of kilometers of flight lines from the ice divide...
This paper discusses the theoretical aspects and applications of a novel methodology for exploiting a knowledge management editor tool to structure organisational knowledge. An organisational knowledge framework for capturing and representing “manufacturing know-how” has been developed using an ontological approach. The delivery mechanism for the application of the captured knowledge makes extensive...
